Improved digital/analogue conversion technique using current splitting in lateral bipolar transistors

open access: yesElectronics Letters, 1988
The letter describes the use of multiple collector lateral bipolar transistors as precision current splitting elements suitable for use in high resolution monolithic D/A convertor design. Multiple collector structures result in better overall linearity and smaller chip area than previously suggested techniques.

Investigation of optical packet routing performance of optical packet switch with optical digital/analogue-conversion-type header processor (wavelength label switch)

open access: yesElectronics Letters, 2003
The dynamic routing operation of optical packets by a novel optical router consisting of an optical digital-to-analogue-conversion-type header processor, an electrically-tunable laser, a semiconductor optical amplifier-based wavelength converter, and an arrayed-waveguide grating router, is reported. A binary header is converted to the single pulse with

Radio Over Fiber Downlink Design for Spatial Modulation and Multi-Set Space-Time Shift-Keying

open access: yesIEEE Access, 2018
Spatial modulation (SM) and multi-set space-time shift-keying (MS-STSK) are capable of striking a flexible design trade-off between the multiplexing and diversity gains attained.

Time‐interleaving design of error‐feedback sigma‐delta modulators with infinite impulse response noise transfer function

open access: yesIET Circuits, Devices and Systems, 2021
Transceivers built to modern communication standards tend to be as digital as possible, including the radio‐frequency stages. This forces the digital‐to‐analogue converters (DACs) in the transmitter section to have a large bandwidth.

Theoretical study of implementing an all-optical analogue-to-digital conversion based on the Mach–Zehnder interferometric configurations [PDF]

open access: yes, 2010
A new technique of ultrafast analogue-to-digital (A-D) conversion for an all-optical data processing is proposed. This technique is based on the Kerr nonlinearity-induced cross-phase modulation in single-mode Mach–Zehnder interferometer configurations ...

A 10 MHz‐BW 85 dB‐SNDR 4th‐order sturdy MASH 2‐0 noise shaping SAR ADC with 2nd‐order gain‐error‐shaping technique

open access: yesElectronics Letters
The multi‐stage noise shaping (MASH) ΣΔ ADC has a good potential to achieve high‐order noise shaping (NS) and high resolution. However, it suffers from quantization noise leakage caused by the mismatch between the analogue NS filter and the digital ...
